CAR REPLACER AND DERAILER.

SPECIFIGATION forming part of Letters Patent No. 496,055, dated April25, 1893.

Application filed June 11, 1892. Serial No. 436,371. (No model.)

T0 at whom it may concern:

Be it known that I, DANIEL D. GREEN, a citizen of the United States,residing at Scofield, in the county of Emery and Territory of Utah, haveinvented a new and useful Oar Replacer and Derailer, of which thefollowing is a specification.

The invention relates to improvements in car replacers and derailers.

The object of the present invention is to provide a simple andinexpensive and strong and durable car replacer and derailer, adapted tobe readily attached to rails, and capable of enabling cars after beingreplaced on the rails to be moved backward and forward over it withoutliability of accidentally derailing them.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings and pointed out in the claim hereto appended.

In the drawings-Figure 1 is a perspective View of a car replacer andderailer constructed in accordance with this invention. Fig. 2 is atransverse sectional view. Fig. 3 is a plan view showing the frogsarranged for derailing.

Like numerals of reference indicate corresponding parts in all thefigures of the drawings.

1 and 2 designate right and left hand frogs provided in their lowerfaces with longitudinal grooves 3, and adapted to be placed upon rails 4which fit in said grooves and have the frogs secured to them byhorizontal bolts or screws 5 arranged at the inner and outer sides ofthe frogs, and engaging under the heads of the rails. The frogs fitsnugly to the rails and are supported by them, and may therefore be of amuch lighter construction than could be employed were they not supportedthroughout their lengths by the rails. The upper faces of the frogspresent a general incline from the middle to the ends 6, which rest uponthe rails, and to the ends 7 which are supported by cross ties and arearranged adjacent to the rails and form inclines up which the wheels ofa car to be replaced ride. The right hand frogl or that one whichreplaces the wheel outside the rails is provided with a longitudinalguiding groove 8 in which the flange of the wheel runs, and it isprovided with a guard point 9 arranged over the rail adjacent to thepoint where the groove diverges from the rail and adapted to prevent theflange of a wheel approaching it from the end 6 of the frog fromfollowing the path of the guide groove, and becoming derailed, therebyenabling the Wheel to move backward and forward over the frog withoutliability of becoming derailed. The left hand frog 2 which replaces theinside wheel and which in the operation of replacing receives the flangeof the Wheel is provided with a longitudinal groove or way 9', and aguard point 10 and the longitudinal groove or way enables the wheel tomove backward and forward over the left hand frog without becomingderailed. The left hand frog is also provided with a guiding groove 11to enable it to be employed as a right hand frog in case a right handfrog should become broken, and the guiding groove 11 forms a guard point12, which when the frog is employed on the right hand side, is adaptedto engage the flange of the wheel to prevent the wheel following thegroove 11.

In replacing a car, the frogs are arranged as illustrated in Fig. 1 ofthe accompanying drawings with the right hand frog arranged to receivethe outside wheel and in Fig. 3 of the accompanying drawings, the frogsare reversed for derailing a car.

It will be seen that the frogs are simple and inexpensive inconstruction and are adapted to enable a car to be readily replaced orderailed, and that they are supported by the rails and may be of lightconstruction. It will also be apparent that after a car has beenreplaced the wheels may move backward and forward over the deviceswithout liability of accidentally derailing the car which is of greatadvantage.

What I claim isy In a car replacer a reversible frog adapted to be usedon either rail and having a rail receiving groove in its lower face andinclini I i ing from its middle to its ends, and having a my own I havehereto afflxed my signature in longitudinal groove 01' way in its upperface the presence of two Witnesses. and provided with the guide point 10and having an angularly disposed guiding groove DAN IEL GREEN 5 11forming a stationary point 12, substan- Witnesses:

tially as and for the purpose described. J. H. EOCLES,

In testimony that I claim the foregoing as J. E. INGLES.
